How do trees decide when and where their branches grow?
In: Biology
Trunk grows up.
Branch comes out a side.
Next branch needs to grow out a different side, to not block light to the first branch.
Next branch again needs to grow out a different angle, to not block light going to first two branches.
So branches need to grow out at an angle that minimises interference with previous branches.
Turns out, the best angle is the golden ratio.
